PLOW ATTACHM ENT.

SPECIFICATION forming part of Letters Patent No. 664,527, dated December25, -1900.

Application filed August 4, 1,900. Serial No. 25,902. (No modeLl To a/ZZwhom it may concern;

Be it known that I, WILLIAM B. BRACE- WELL, a citizen of the UnitedStates, residing at otton, in the county of Grimes and State of Texas,have invented a new and useful Plow Attachment, of which the followingis a specification. Y A

The present invention relates to improvements in plows, the object beingto provide an attachment in the form of a shoe that may be applied toany ordinary plow and which sion of novel means for securing the shoe inplace, said securing means being adjustable in order that the attachmentmay be applied to different styles of plows and the position of the shoeon the plow changed as desired to meet the different kinds of work.

In order that the invention may be readily understood by those skilledin the art, the preferred form is illustrated in the accompanyingdrawings and described in the following specification, of which the saiddrawings `form a part.

In the drawings, Figure 1 is a perspective view of an ordinaryshovel-plow, showing the improved attachment placed thereon. Fig. 2 is aperspective View of the same looking in an opposite direction. Fig. 3 isa longitudinal section. Fig. 4. is a detail perspective of the shoe.Fig. 5 is a detail perspective of the angle-bracket.

Similar numerals of reference designate corresponding parts in theseveral figures of the drawings.

In order that the application of the device may be clearly understood,anordinary shovelplow is illustrated, of which 10 designates the beam; 11,the standard, which comprises a pair of spaced arms whose upper endsembrace the beam, and 12 the shovel-sweep or moldboard, secured to thelower end of the standard 11.

The improvement comprises a furrow shoe or slide 13, secured to thelower end of the plow by means of the angle-bracket 14.. The

shoe 13 consists of a metallic bar rectangular in cross-section andhaving at one end the baekwardly-extending upturned lip 15, that isslightly curved and forms a notch 16, in which the point of the plow issecured. This end of the shoe is broadened slightly and is pointed,forming a nose which works in advance of the shovel and loosens theearth and root-s. In order to strengthen the point of the shoe, a rivet17 is arranged vertically through the shoe and lip at their points ofintersection, thus obviating any liability ot breaking at this point.The shoe is also provided with a pair of bolt-holes 18, which passvertically through the same and receive bolts 19, by means of which theshoe is secured to the angularbracket 14. The angular bracket 14comprises a metallic bar having a longitudinal slot 20 and bent to forma pair of arms 21 and 22, which are adapted to conform to and restagainst the back of the standard and the upper surface of the shoe 13,respectively. The bolts 19 pass through the slot of the arm 22, and nuts23, arranged upon said bolts, engage the upper surface of the'arm, andthereby clamp the shoe rigidly to the same. A bolt 24 is arranged topass through the slot of the arm 21 and through the standard 11.Preferably the same bolt that fastens the shovel is used for clampingthe arm to the standard.

In applying the device the point of the plow is arranged in the notch 16and the angie-bracket Ais adjusted upon the shoe until the arm 21 restsagainst the standard. The nuts 23 are then tightened. By this means itwill be seen that the shoe may be applied to dierent sizes and styles ofplows. In 0rder that the depth of penetration of the plow may beregulated, the angle of inclination of the shoe may be readily changedby adjusting the arm 21 upon the standard. This is done by loosening thenut of the bolt 24, whereupon the slot 2O will allow the arm to beraised or lowered, as desired.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described plow attachment will be readilyapparent to those skilled in the art without further description, and itwill be understood that various changes in the form, proportion, andminor details Vot' IOO construction may be resorted to Without departingfrom the principle or sacrificing any of the advantages of thisinvention.

Having now described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

l. In a plow attachment, the combination with the standard andplow-point, of a furrow-shoe interlocked at one end with the plowpointand extended rearwardly therefrom, and a brace interposed between the'standard and the rearwardlylextended portion of the shoe and rigidlyconnected to both.

2. In a plow attachment, the combination with the standard andplow-point, of a furrow-shoe interlocked at one end with the plowpointand extended rearwardly therefrom, and a brace interposed between thestandard and the rearwardly-extended portion of the shoe and adjustablyconnected to the standard.

3. In a plow attachment, the combination with the standard andplow-point, of a furrow-shoe interlocked at one end with the plowpointand extended rearwardly1 therefrom and a brace interposed between thestandard and the rearwardly-extended portion of the shoe and adjustablyconnected ro the standard at one end and havingalongitudinal adjustableengagement with the shoe at its opposite ends.

4. A plow attachment comprising a shoe adapted to interlock with thepoint of a plow,

and a brace having a longitudinal adj ustabl connection with the shoe,and means for securing said bracket to the plow-standard.

5. A plow attachment comprising a shoe adapted to interlock with thepoint of a plow and have its front end project beyond the front portionof the same,y and a brace hav# ing a longitudinal adjustable connectionwith the shoe, means for securing said brace in ixed position on theshoe; and means for ad# justably securing said bracket to a plow#standard. n Y j 6. In a plow attachment; the combination with thestandard and plow-point; of a furrow-shoe having a detachable`interlocking engagement at one end with the point and extendingrearwardly beyond vthe standard, and an angular brace arranged in theangle formed by said standard and rearwardly-e1@ tending portion of theshoe, the arms of said brace resting flat upon the standard and shoerespectively and provided with slots, and bolts passing through thestandard and shoe respectively so that the shoe is longitudinallyadjustable upon the brace and the brace is longitudinally adjustableupon-the standard.

In testimony1 that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
